The way I understand it is, generally speaking, A chrome lined barrel is more rust resisteant than a SS one but SS barrels are generally a little more accurite so...

...Forgetting price, if you were building a 16" CAR to be used primarly for plinking\target shooting but may also be used as a fall back for your SHTF gun would you use a chrome lined steel barrel or a stainless steel barrel? Please include you reasoning.

Have you seen that Bushmaster will be doing 1/7 chrome lined HBARS special for us for under $170? Thats your barrel right there. You wont find cheaper. My Bushmaster 1/7 M4 will do MOA. Is that accurate enough for you?
